Description

The present invention relates to a closure or solar protection home-automation equipment.
The present invention also relates to a method for recharging a battery for such closure or solar protection home-automation equipment.
In general, the present invention relates to the field of concealing devices comprising a motorized drive device setting a screen in motion between at least one first position and one second position.
A motorized drive device comprises an electromechanical actuator for a movable element for closing, blacking out or providing solar protection, such as a blind or any other equivalent material, hereinafter referred to as a screen.
Document WO 2006/091303 A1 is already known, which describes a closure or solar protection home-automation equipment.
The concealing device comprises a housing, a winding tube, a screen, a load bar, a motorized drive device and an autonomous electrical energy supply device.
A first end of the screen is positioned at the housing. Additionally, a second end of the screen is fastened to the load bar.
The motorized drive device comprises an electromechanical actuator making it possible to raise and lower the screen, between a high position and a low position and, more particularly to wind and unwind the screen, between a wound position and an unwound position. The electromechanical actuator is electrically connected to the autonomous electrical energy supply device.
The autonomous electrical energy supply device comprises a battery. The battery is positioned at the housing of the concealing device and, more particularly, inside a winding tube of the screen. The battery comprises several rechargeable energy storage elements.
The autonomous electrical energy supply device comprises a first electrical connection element and a second electrical connection element.
The first electrical connection element is electrically connected to the battery by an electrical connection. The electrical connection between the first electrical connection element and the battery is implemented using a power supply cable extending along the screen and, more particularly, integrated into the fabric of the screen.
The first electrical connection element is positioned at the load bar of the concealing device and configured to be connected to an external electric supply source, so as to recharge the battery. The first electrical connection element is either an electrical connector, or a coil cooperating with another coil positioned at a threshold of an opening. In this way, the first electrical connection element can be electrically connected to a wall outlet of a power supply network.
The second electrical connection element is positioned at the housing of the concealing device. The electrical connection between the first electrical connection element and the battery is implemented through the second electrical connection element electrically connecting the power supply cable to the battery.
The power supply cable comprises a first part extending between the first electrical connection element and the second electrical connection element, as well as a second part extending between the second electrical connection element and the battery.
However, this home-automation equipment has the drawback of electrically connecting the first electrical connection element, positioned at the load bar of the concealing device, to the battery, positioned at the housing of the concealing device, using a power supply cable extending along the windable fabric of the screen and the second electrical connection element.
Thus, the power supply cable electrically connecting the first electrical connection element to the battery is wound with the screen around the winding tube, when the screen is moved toward the wound position.
In this way, the second electrical connection element, connecting the power supply cable to the battery, is subject to stresses exerted during the unwinding and the winding of the screen.
Consequently, the electrical connection between the first electrical connection element and the battery can be damaged during use of the home-automation equipment.
The integration of the power supply cable into the windable fabric of the screen may also cause damage to the latter during the unwinding and winding of the screen around the winding tube.
Furthermore, the integration of the power supply cable into the windable fabric is detrimental to the aesthetics of the screen.
Furthermore, the electrical connection between the power supply cable and the battery is complex to carry out, since the power supply cable is wound around the winding tube of the screen.
The present invention aims to resolve the aforementioned drawbacks and to propose home-automation equipment for closure or solar protection making it possible to simplify an electrical connection between a first electrical connection element positioned at a load bar of a concealing device and a battery positioned at a housing of the concealing device, so as to be able to recharge the battery from an external electrical supply source, while guaranteeing the reliability of this electrical connection and minimizing the costs of obtaining the home-automation equipment.
In this respect, according to a first aspect, the present invention relates to home-automation equipment for closure or solar protection comprising a concealing device,
the concealing device comprising at least:

- a screen,
- a device for holding the screen, a first end of the screen being positioned at the holding device of the screen,
- a load bar, a second end of the screen being fastened to the load bar,
- a motorized drive device, and
- an autonomous electrical energy supply device,

the motorized drive device comprising at least:

- an electromechanical actuator making it possible to raise and lower the screen, between a high position and a low position, the electromechanical actuator being electrically connected to the autonomous electrical energy supply device,

the autonomous electrical energy supply device comprising at least:

- a battery, the battery being positioned at the holding device of the screen,
- a first electrical connection element, the first electrical connection element being positioned at the load bar of the concealing device, the first electrical connection element being configured to be connected to an external electrical supply source, so as to recharge the battery, and
- a second electrical connection element, the second electrical connection element being positioned at the holding device of the screen.

According to the invention, the second electrical connection element cooperates with the first electrical connection element only when the screen is in a recharging position of the battery, the recharging position of the battery corresponding either to the high position of the screen or to a position of the screen where the load bar is near the holding device of the screen, so as to establish an electrical connection between the first electrical connection device positioned at the load bar and the battery positioned at the holding device of the screen.
Thus, the electrical connection between the first electrical connection element, positioned at the load bar of the concealing device, and the battery, positioned at the holding device of the screen, is implemented only when the first electrical connection element is positioned near the second electrical connection element, so as to be able to recharge the battery.
In this way, the electrical connection between the first electrical connection element, positioned at the load bar, and the battery, positioned at the holding device of the screen, is implemented without a power supply cable connecting the first electrical connection element to the second electrical connection element, so as to guarantee the reliability of this electrical connection and to minimize the costs of obtaining the home-automation equipment.
Furthermore, the positioning of the first electrical connection element at the load bar of the concealing device makes it possible to facilitate, for the user, the electrical connection of the external electrical supply source to the first electrical connection element, since this electrical connection between the first electrical connection element and the external electrical supply source can be done when the screen of the concealing device is in the low position.
Moreover, the battery can be recharged without having to disassemble part of the home-automation equipment and, in particular, the holding device of the screen.
In a first embodiment, the first and second electrical connection elements comprise electrical contact elements, so as to establish electrical conduction between the first and second electrical connection elements, when the screen is in the recharging position of the battery.
In a second embodiment, the first and second electrical connection elements comprise coils, so as to establish electromagnetic coupling between the first and second electrical connection elements, when the screen is in the recharging position of the battery.
Advantageously, the first electrical connection element is mounted on the load bar of the concealing device by fastening elements.
Preferably, these fastening elements are holding elements bearing on walls of the load bar.
According to one preferred feature of the invention, the first electrical connection element comprises a centering element cooperating with a centering element of the second electrical connection element, so as to center the first electrical connection element relative to the second electrical connection element, in the assembled configuration of the concealing device and when the screen is in the recharging position of the battery.
According to another preferred feature of the invention, the first electrical connection element comprises a first part and a second part, the second part being movable relative to the first part.
Advantageously, the first and second parts of the first electrical connection element respectively comprise a recess cooperating with the load bar, the recesses of the first and second parts of the first electrical connection element forming at least part of the fastening elements of the first electrical connection element on the load bar of the concealing device.
Preferably, the first and second parts of the first electrical connection element are kept bearing on walls of the load bar using an elastic return element.
According to another preferred feature of the invention, the first electrical connection element comprises a centering element cooperating with a centering element of the load bar, so as to position the first electrical connection element relative to the load bar and to center the first electrical connection element relative to the second electrical connection element, in the assembled configuration of the concealing device.
According to a second aspect, the present invention relates to a method for recharging a battery for a home-automation equipment for closure or solar protection as set out above.
According to the invention, this method comprises at least the following steps:

- lowering the screen toward the low position,
- connecting an external electrical supply source on the first electrical connection element,
- raising the screen to the recharging position of the battery, and
- making an electrical connection between the first and second electrical connection elements, so as to supply electrical energy to the battery from the external electrical supply source.

This method for recharging a battery has features and advantages similar to those previously described, relative to the home-automation equipment according to the invention.

FIG. 7 is a schematic view similar to FIG. 6 and from another angle, where a cover of the second electrical connection element has been removed.

In reference to FIGS. 1 and 2, we will first describe home-automation equipment according to the invention and installed in a building comprising an opening 1, window or door, equipped with a screen 2 belonging to a concealing device 3, in particular a motorized windable blind.
The concealing device 3 may be a blind, in particular made from fabric, that is windable, pleated or with slats.
The concealing device 3 comprises a holding device 9, 23 of the screen 2.
A windable blind according to one embodiment of the invention will be described in reference to FIGS. 1 and 2.
The screen 2 of the concealing device 3 is wound on a winding tube 4 driven by a motorized drive device 5 and movable between a wound position, in particular an upper position, and an unwound position, in particular a lower position.
The moving screen 2 of the concealing device 3 is a closure, concealing and/or solar protection screen, winding on the winding tube 4, the inner diameter of which is generally substantially greater than the outer diameter of an electromechanical actuator 11, such that the electromechanical actuator 11 can be inserted into the winding tube 4 during the assembly of the concealing device 3.
The motorized drive device 5 comprises the electromechanical actuator 11, in particular of the tubular type, making it possible to set the winding tube 4 in rotation so as to unwind or wind the screen 2 of the concealing device 3.
The concealing device 3 comprises the winding tube 4 for winding the screen 2, where, in the mounted state, the electromechanical actuator 11 is inserted into the winding tube 4.
The concealing device 3 also comprises a load bar 8 for exerting tension on the screen 2.
In a known manner, the windable blind, which forms the concealing device 3, includes a fabric, forming the screen 2 of the windable blind 3. A first end of the screen 2, in particular the upper end of the screen 2 in the assembled configuration of the concealing device 3 in the home-automation equipment, is fastened to the winding tube 4. Additionally, a second end of the screen 2, in particular the lower end of the screen 2 in the assembled configuration of the concealing device 3 in the home-automation equipment, is fastened to the load bar 8.
Here, the fabric forming the screen 2 is made from a textile material.
In an example embodiment that is not shown, the first end of the screen 2 has an eyelet through which a rod is positioned, in particular made from plastic. This eyelet made at the first end of the screen 2 is obtained using a seam of the fabric forming the screen 2. During the assembly of the screen 2 on the winding tube 4, the eyelet and the rod situated at the first end of the screen 2 are inserted by sliding in a slot arranged on the outer face of the winding tube 4, in particular over the entire length of the winding tube 4, so as to be able to wind and unwind the screen 2 around the winding tube 4.
In the case of a windable blind, the high wound position corresponds to a predetermined high end-of-travel position, or to setting in support of the load bar 8 of the screen 2 against an edge of a housing 9 of the windable blind 3, and the low unwound position corresponds to a predetermined low end-of-travel position, or to the beginning of bearing of the load bar 8 of the screen 2 against a threshold 7 of the opening 1, or to complete unwinding of the screen 2.
The winding tube 4 is positioned inside the housing 9 of the windable blind 3. The screen 2 of the windable blind 3 winds and unwinds around the winding tube 4 and is housed at least partially inside the housing 9.
In general, the housing 9 is positioned above the opening 1, or in the upper part of the opening 1.
The housing 9 is an integral part of the holding device 9, 23 of the screen 2.
In one embodiment illustrated in FIG. 2, the screen 2 also includes, at each of its lateral edges, a fastening part 10 in the form of a strip. The fastening parts 10 form an overthickness at each lateral edge of the screen 2. The home-automation equipment comprises two lateral guideways 6 positioned along two lateral edges of the opening 1. The lateral guideways 6 additionally respectively comprise a groove inside which a fastening part 10 of the screen 2 is retained, as well as a lateral end of the load bar 8 fastened to the second end of the screen 2.
Thus, during the winding or unwinding of the screen 2, the fastening parts 10 fastened on the lateral edges of the screen 2 and the lateral ends of the load bar 8 fastened to the second end of the screen 2 are retained in the lateral guideways 6, so as to guarantee lateral guidance of the screen 2.
Each groove arranged in a lateral guideway 6 makes it possible to prevent the withdrawal of a fastening part 10 fixed on one of the lateral edges of the screen 2, during the movement of the screen 2 between the wound position and the unwound position.
Preferably, each fastening part 10 extends along the entire length of one of the two lateral edges of the screen 2.
In one example embodiment, the fastening parts 10 are respectively fastened at a lateral edge of the screen 2 by gluing, welding or overmolding. Additionally, the fastening parts 10 can be made from plastic and, in particular, overmolded on the lateral edges of the screen 2.
Here, the lateral guideways 6 respectively positioned along a lateral edge of the opening 1 extend along a vertical direction. The lateral guideways 6 extend from the threshold 7 of the opening 1 to the housing 9 of the windable blind 3.
Advantageously, trim elements, not shown, are positioned inside lateral guideways 6 and cooperate with the fastening parts 10 respectively fastened at a lateral edge of the screen 2, so as to keep the screen 2 stretched by applying a force on each fastening part 10 against a wall of the lateral guideway 6.
For example and non-limitingly, the trim elements positioned inside the lateral guideways 6 are provided with elastics, in particular made from plastic. The trim elements can also be provided in the form of foam or include a fly.
Thus, the trim elements positioned inside the lateral guideways 6 make it possible to guarantee the application of a frictional resistance on the fastening parts 10 of the screen 2, so as to keep the screen 2 stretched, during a movement of the screen 2 or when the screen 2 is kept stopped.
Advantageously, the housing 9 of the blind 3 and the side guideways 6 form a frame inside which the screen 2 can be moved. This frame can be closed by an additional bar connecting the two lateral guideways 6 at the threshold 7 of the opening 1.
The motorized drive device 5 is controlled by a control unit. The control unit may for example be a local control unit 12, where the local control unit 12 can be connected through a wired or wireless connection with a central control unit 13. The central control unit 13 drives the local control unit 12, as well as other similar local control units distributed throughout the building.
The central control unit 13 can be in communication with a weather station located outside the building, in particular including one or more sensors that can be configured for example to determine a temperature, brightness, or wind speed.
A remote control 14, which can be a type of local control unit, and provided with a control keypad, which comprises selection and display means, further allows a user to intervene on the electromechanical actuator 11 and/or the central control unit 13.
The motorized drive device 5 is preferably configured to carry out the unwinding or winding commands of the screen 2 of the concealing device 3, which may in particular be acquired by the remote control 14.
The electromechanical actuator 11 belonging to the home-automation equipment of FIGS. 1 and 2 will now be described in reference to FIG. 3.
The electromechanical actuator 11 comprises an electric motor 16. The electric motor 16 comprises a rotor and a stator, not shown and positioned coaxially around a rotation axis X, which is also the rotation axis of the winding tube 4 in the assembled configuration of the motorized drive device 5.
Control means for controlling the electromechanical actuator 11, making it possible to move the screen 2 of the concealing device 3, comprise at least one electronic control unit 15. This electronic control unit 15 is able to operate the electric motor 16 of the electromechanical actuator 11, and in particular to allow the supply of electrical energy for the electric motor 16.
Thus, the electronic control unit 15 in particular controls the electric motor 16, so as to open or close the screen 2, as previously described.
The electronic control unit 15 also comprises a module for receiving control orders, the control orders being sent by an order transmitter, such as the remote control 14 designed to control the electromechanical actuator 11 or one of the local 12 or central 13 control units.
Preferably, the control orders receiving module of the electronic control unit 15 is of the wireless type. In particular, the control orders receiving module is configured to receive radio control orders.
The control orders receiving module can also allow the reception of control orders sent by wired means.
The control means of the electromechanical actuator 11 comprise hardware and/or software means.
As one non-limiting example, the hardware means may comprise at least one microcontroller.
The electromechanical actuator 11 is supplied with electrical energy by a battery 24. The electromechanical actuator 11 makes it possible to move the screen 2 of the concealing device 3.
Here, the electromechanical actuator 11 comprises a power supply cable 18 making it possible to supply electrical energy from the battery 24.
The casing 17 of the electromechanical actuator 11 is preferably cylindrical.
In one embodiment, the casing 17 is made from a metal material.
The material of the casing of the electromechanical actuator is in no way limiting and may be different, and in particular made from plastic.
The electromechanical actuator 11 also comprises a reducing gear device 19 and an output shaft 20.
The electromechanical actuator 11 may also comprise an end-of-travel and/or obstacle detection device, which may be mechanical or electronic.
Advantageously, the electric motor 16 and the reducing gear device 19 are positioned inside the casing 17 of the electromechanical actuator 11.
The output shaft 20 of the electromechanical actuator 11 is positioned inside the winding tube 4, and at least partially outside the casing 17 of the electromechanical actuator 11.
The output shaft 20 of the electromechanical actuator 11 is coupled by a connecting means 22 to the winding tube 4, in particular using a wheel-shaped connecting means.
The electromechanical actuator 11 also comprises a closing off element 21 for one end of the casing 17.
Here, the casing 17 of the electromechanical actuator 11 is fastened to a support 23, in particular a flange, of the housing 9 of the concealing device 3 using the closing off element 21 forming a torque pin, in particular a closing off and torque-reacting head. In such a case where the closing off element 21 forms a torque pin, the closing off element 21 is also called a fixed point of the electromechanical actuator 11.
The support 23 is also an integral part of the holding device 9, 23 of the screen 2. Here and as illustrated in FIG. 3, the electronic control unit 15 is positioned inside the casing 17 of the electromechanical actuator 11.
Thus, the electronic control unit 15 is incorporated inside the casing 17 of the electromechanical actuator 11.
In another embodiment, the electronic control unit 15 is positioned outside the casing 17 of the electromechanical actuator 11, and in particular, mounted on the support 23, in the closing off element 21 or in the housing 9.
Certain parts of the concealing device 3 will now be described in reference to FIGS. 4 to 7.
The load bar 8 of the concealing device 3 comprises a lower wall 40, an upper wall 41 and two side walls 42, in the assembled configuration of the concealing device 3.
The housing 9 of the concealing device 3 comprises a lower wall 43, an upper wall, not shown in FIG. 4 but visible in FIG. 2, and two side walls 44, in the assembled configuration of the concealing device 3. For the clarity of the drawing, the lower wall 43 is not shown in FIG. 2.
The concealing device 3 comprises an autonomous electrical energy supply device 26, in that it makes it possible to power the electromechanical actuator 11, without itself being connected to the sector grid. The electromechanical actuator 11 is electrically connected to the autonomous electrical energy supply device 26.
The autonomous electrical energy supply device 26 comprises the battery 24. The battery 24 is positioned at the holding device 9, 23 of the screen 2 and, more particularly, of the housing 9 of the concealing device 3.
Here, the battery 24 is positioned inside the housing 9.
Alternatively, the battery 24 is positioned outside the housing 9.
Here and as illustrated in FIG. 4, the battery 24 is directly electrically connected to the electronic control unit 15 by the power supply cable 18.
Advantageously, the motorized drive device 5 and, in particular the electronic control unit 15, comprises charging elements configured to charge the battery 24 from the electrical energy supplied by an external electrical supply source 25.
Here, the battery 24 is of the rechargeable type and supplies electric energy to the electromechanical actuator 11.
The battery 24 comprises one or several energy storage elements. The energy storage elements of the battery 24 can in particular be rechargeable cells.
The autonomous electrical energy supply device 26 comprises a first electrical connection element 27 and a second electrical connection element 28.
The first electrical connection element 27 is positioned at the load bar 8 of the concealing device 3.
The first electrical connection element 27 is configured to be connected to an external electrical supply source 25, so as to recharge the battery 24.
As one non-limiting example, the external electrical supply source 25 is a charger able to be connected on a wall outlet, so as to recharge the battery 24 from an electric supply grid.
In practice, the first electrical connection element 27 comprises an electrical connector 31.
Here, the electrical connector 31 of the first electrical connection element 27 is configured to cooperate with an electrical connector 32 connected by a power supply cable 33 to the external electrical supply source 25.
The second electrical connection element 28 is positioned at the holding device 9, 23 of the screen 2 and, more particularly, of the housing 9 of the concealing device 3.
The second electrical connection element 28 cooperates with the first electrical connection element 27 only when the screen 2 is in a recharging position of the battery 24, so as to establish an electrical connection between the first electrical connection element 27 and the battery 24.
The recharging position of the battery 24 corresponds either to the high position of the screen 2 or to a position of the screen 2 where the load bar 8 is close to the holding device 9, 23 of the screen 2.
According to the present invention, it may be considered that the load bar 8 is close to the holding device 9, 23 when the load bar 8 is situated above the opening 1.
Thus, the electrical connection between the first electrical connection element 27 and the battery 24 is implemented only when the first electrical connection element 27 is positioned near the second electrical connection element 28, so as to be able to recharge the battery 24.
In this way, the electrical connection between the first electrical connection element 27 and the battery 24 is implemented without a power supply cable connecting the first electrical connection element 27 to the second electrical connection element 28, so as to guarantee the reliability of this electrical connection and to minimize the costs of obtaining the home-automation equipment.
Furthermore, the positioning of the first electrical connection element 27 at the load bar 8 of the concealing device 3 makes it possible to facilitate, for the user, the electrical connection of the external electrical supply source 25 to the first electrical connection element 27, since this electrical connection between the first electrical connection element 27 and the external electrical supply source 25 can be done when the screen 2 of the concealing device 3 is in the low position.
Moreover, the battery 24 can be recharged without having to disassemble part of the home-automation equipment and, in particular, the holding device 9, 23 of the screen 2, in particular of the housing 9 of the concealing device 3.
Advantageously, the recharging position of the battery 24 can be determined during the installation of the concealing device 3 and, in particular, during the learning of the high and low end-of-travel positions of the screen 2.
In one example embodiment, the recharging position of the battery can be determined as being reached owing to a metering device, in particular counting the number of revolutions of the output shaft 20 of the electromechanical actuator 11, or the operating time of the electromechanical actuator 11.
Alternatively, the recharging position of the battery can be determined as being reached using the device detecting the end of travel and/or an obstacle of the electromechanical actuator 11.
In a first embodiment, as illustrated in FIGS. 5 to 7, the first and second electrical connection elements 27, 28 comprise electrical contact elements 29, 30, so as to establish electrical conduction between the first and second electrical connection elements 27, 28, when the screen 2 is in the recharging position of the battery 24.
Thus, the electrical connection between the first electrical connection element 27, positioned at the load bar 8, and the battery 24, positioned at the holding device 9, 23 of the screen 2, is implemented only when the first electrical connection element 27 is pressed against the second electrical connection element 28.
In this way, the electrical connection between the first electrical connection element 27 and the battery 24 is implemented only when the screen 2 is in the recharging position of the battery 24.
The electrical connection between the first and second electrical connection elements 27, 28 is interrupted once the screen 2 is in a position different from the recharging position of the battery 24.
Here, the recharging position of the battery 24 is defined by the setting in support of the electrical contact elements 29 of the first electrical connection element 27 with the electrical contact elements 30 of the second electrical connection element 28.
Preferably, the recharging position of the battery 24 is determined as being reached when the electrical contact elements 29 of the first electrical connection element 27 are placed in contact with the electrical contact elements 30 of the second electrical connection element 28, so as to send a signal to the electronic control unit 15.
Thus, following reception of this signal by the electronic control unit 15, the latter emits a control order to stop the electromechanical actuator 11.
In this way, the movement of the first electrical connection element 27 relative to the second electrical connection element 28 is controlled by the electronic control unit 15 and, more particularly, by the movement of the screen 2 through the electromechanical actuator 11.
In the example embodiment illustrated in FIGS. 5 to 7, the first electrical connection element 27 comprises two electrical contact elements 29. Furthermore, the second electrical connection element 28 comprises two electrical contact elements 30.
The electrical contact elements 29 of the first electrical connection element 27 cooperate with the electrical contact elements 30 of the second electrical connection element 28, when the screen 2 is in the recharging position of the battery 24.
Here, the electrical contact elements 29, 30 of the first and second electrical connection elements 27, 28 are electrical connection studs. Each electrical connection stud 29 comprises an electrical contact surface cooperating with an electrical contact surface of one of the electrical connection studs 30.
Here, the electrical contact elements 29 of the first electrical connection element 27 are positioned at an upper part 34 of the first electrical connection element 27 and the electrical contact elements 30 of the second electrical connection element 28 are positioned at a lower wall 35 of the second electrical connection element 28, in the assembled configuration of the concealing device 3.
In practice, the electrical contact elements 30 of the second electrical connection element 28 are electrically connected to the battery 24 using electrical supply wires, not shown.
In a second embodiment, not shown, the first and second electrical connection elements 27, 28 comprise coils, so as to establish electromagnetic coupling between the first and second electrical connection elements 27, 28, when the screen 2 is in the recharging position of the battery 24.
Thus, the electrical connection between the first electrical connection element 27 and the battery 24 is implemented only when the first electrical connection element 27 is positioned at a distance from the second electrical connection element 28 smaller than or equal to a maximum threshold value.
This maximum threshold value depends on the coils and may be about several millimeters, so as to guarantee the electromagnetic coupling between the first and second electrical connection elements 27, 28.
In this way, the electrical connection between the first electrical connection element 27 and the battery 24 is implemented only when the screen 2 is substantially in the high position.
The positioning of the first and second electrical connection elements 27, 28 comprising coils makes it possible to form a transformer, so as to conduct the electrical energy from the first electrical connection element 27 toward the second electrical connection element 28.
The electromagnetic coupling between the first and second electrical connection elements 27, 28 is interrupted once the screen 2 is in a position different from the recharging position of the battery 24, where the distance between the first and second electrical connection elements 27, 28 is greater than the threshold value.
Here, the recharging position of the battery 24, corresponding to the position of the screen 2 where the load bar 8 is close to the holding device 9, 23 of the screen 2, is defined by the positioning of the coil of the first electrical connection element 27 relative to the coil of the second electrical connection element 28, so as to establish the electromagnetic coupling between the first and second electrical connection elements 27, 28.
